Katie McGinty spent months trailing in the polls against Republican incumbent Pat Toomey, but in recent weeks, has gained a slight advantage. Senator Bob Casey, said a McGinty win would be historic.

McGinty challenged Toomey’s record on tax credits and education, as well as his failure to take a stand on presidential Nominee Donald Trump.
